I just noticed a beautiful spot in Beijing: Holy Lotus Mountain "Sheng Lian Shan".

Well, I don't know your exact starting place that cannot provide the detailed transportation. For example, you can take bus no.47 from Jishuitan to Changchui Street West first. Then transfer to bus no.901 to Yanhua Donglichang and bus no.Fang24 to Shenglianshan Bus Stop. After arriving, just walk northwest around 150 meters to find the southwest gate of the scenic area.
